Electrical stimulation treatment has become one of the most important treatment means after several centuries'development. These treatment means have simple operation, wide-ranging, and can make important contributions to many patients what keep away form ailments and come back a healthy life. Many stimulation treatment equipments based on electrical stimulation have appeared now, for example, some equipment are based on the tradition Chinese acupuncture, and some are based on the cerebellar nucleus stimulation that the rising nerve central protection theory. Whether electrical stimulation equipment is, however, a relevant stimulation way should be setting according to different treatment means.Organisms are complex nonlinear system. Nonlinear research is becoming the new direction of the nerve system. These research not only can accurately reflect the chaos expression of the body under pathological, but also can apperceive minimal outside stimulation, and make corresponding reactivity.This paper analyzes the action potential mechanism of neurons when outside stimulation brings, and the nonlinear characteristics of different neurons action potential are analyzed, then we develop a whole system that can assist electrical stimulation optimization.This whole system includes the neurons action simulation system, neurons action potential conduction simulation system, and neurons self-excited oscillation simulation system. The system can exactly reflect the bioelectricity characteristics of neurons that through different stimulation waveforms and different stimulation parameters according to the request of experiment. The action potential released effects of different combination stimulation can be observed through the action potential nonlinear analysis after stimulus. The system can provide a theory foundation for the stimulation choices of therapeutic equipment.At the same time, this paper try to show that the treatment of Chaos Control is reasonable, which is widely used in recent years. This research can provide a better guidance for further study of chaotic control theory. In addition, the modulated electrical stimulation are also widely used in electrical stimulation, a preliminary analysis of the spectrum revealed the distinction between ordinary and the different effects on the body with the modulated electrical stimulation, which will help to develop the mid-frequency modulator for the further development of electrical stimulation.
